Taking Au-Ag intergrowth compounds as an example this paper has reached the following conclusions. In the Au-Ag compounds of differem types of gold deposits as sequemially replaces Au, making up a continuous isomorphous series. The content of Au and Ag in native gold forms a regular pattern. The development of native gold and that of electrum have something to do with different types of gold deposits respectively. Abundances of trace elements in Au-Ag minerals are controlled by geological settings and geochemical fields. The above study provides new geological information and a new method for the study and exploration of gold deposits.
